Add transfer permission to FT

[harrywong]

Currently we only support transfer permission in NFT domain not in FT. We'd like to add transfer permission to FTs for better flexibility. And due to this flexibility, users may not notice there's a chance that the issuer of FT can change the transfer permission at any time. Additional reserved meta field .disable-set-transfer will be added for explicit declaration of cannot setting transfer permission.

transfer permission is already implemented in everiToken 3.1 (FT v2).
